摘　　要：利用Workbench对立式加工中心的复合筋床身结构进行拓扑优化,根据优化结果,在原结构基础上增加了两个出砂孔,以及增大床身底部筋格的面积,高速立式加工中心是处于运动状态的,针对工作台处于三种不同的极限工况(左极限、居中、右极限),对改进后的床身结构进行静力分析,通过对分析结果进行比较可知改进后的床身结构在X、Y、Z这3个方向的变形量都减小,说明改进后的床身结构的静态性能得到提高,分析结果为同类床身结构的改进设计提供了参考和思路。Analyzes the composite reinforced body structure of the vertical machine center by using Workbench,according to the optimization results,the original structure adds two sand holes on the basis,and increases the area of the bed bottom reinforcement lattice,high-speed vertical machining center is in motion,according to the table in three different limit conditions（ left limit,the middle,right limit）,makes the static analysis for the improved structure,through the comparison of the analysis results shows that the deformation of structure in X,Y,Z direction is reduced,indicates that the static performance of bed body structure is improved,the results provide reference and ideas to improve the design of the similar bed structure.
